Explanation:

C4 plants are a categorical plant which has been categorized based on their photosynthetic pathways. Usual photosynthetic process involves a PCR pathway which refers to be C3 cycle and plants hence called C3 cycle. C4 is an adaption to this pathway.

C4 pathway overcomes the photo-respiration limits of C3 cycle, and this helps to retain water much more and thus can be sought to adapt in the drier climate or drought. It can also withstand higher amount of Carbon dioxide concentration.
